I know what you mean, sometimes it seems that little kids always have a runny nose. I've assumed it would be a long-term bad thing if we don't allow for this.

I know what you mean, sometimes it seems that little kids always have a runny nose. I've assumed it would be a long-term bad thing if we don't allow for this. Perhaps it is better for kids to encounter all these rhinoviruses and coronaviruses when they are young. Maybe a lot of them are like covid-19, easy to fend off when young but deadly when older. Maybe that is why people sometimes die of the common cold, because they never caught that particular virus when young.
